Metal-polish.



UNITED; STATES PATENT OFFICE.

AMBROSE RIDD, OF NEWPORT, KENTUCKY.

METAL-POLISH.

No Drawing.

To all whom it may concern:

Be it known that I, AMBROSE R101), a citizen of the United States, residing at Newport, in the county of Campbell and State of Kentucky, have invented a new and useful Metal-Polish, of which the following is a specification.

This invention relates to metal polishes.

The object of the invention is, in a rapid, economical and practical manner, to produce a polish on metallic surfaces, such as gas and coal stoves, furnaces, stove pipes, and the like, that will be hard, durable and highly heat resistant, and which will impart to the article treated an appearance of a finely polished enamel surface;

A further object of this invention is to render unnecessary any baking of the polish, thus materially to lessen the cost and the labor incident to imparting a finish to treated surfaces.

A further object of the invention is to dispense with the use of benzin, gasolene and naphtha, on account of the explosive nature of these oils, and to substitute therefor turpentine as being far safer and as yielding better results.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel metal polish, as will be hereinafter fully described and claimed.

In carrying the invention into effect, the following ingredients are employed substant l l ure: varnish, (copaL) one part; turpentine, one part; boiled linseed oil, one twelfth part; turpentine asphaltum, one eighth part; graphite, flake or powdered form, uantum sufiicizf.

The linseed oil is first dissolved in the turpentine and then the turpentine asphaltum is added after which the varnish is included and admixed with the other ingredients. There is then stirred into the mixture a sufficient quantity of powdered or finely flaked graphite to bring the mass to the consistency of thick house paint. As under difierent requirements, the quantity of graphite will vary, it is impossible to state the amount used any more definitely than that above given.

Specification of Letters Patent.

Application filed October 2, 1911.

Patented May 21, 1912.

Serial No. 652,376.

With the compound thus described, in order to secure a highly polished surface, it will only be necessary to apply the polish with a soft ,cloth, and then carefully wipe oil the surplus, and after permitting the coating to dry for a few seconds, finish by rubbing or brushing in the ordinary manner.

The functions secured by the different ingredients are as follows: The varnish acts as an adhesive to fix the graphite to the treated surface. The turpentine operates to hold the mixture in fluid condition until used. The linseed oil acts to retard slightly the drying of the compound in order to permit the proper brushing or rubbing necessary to secure the desired polish, the turpentine asphaltum is to impart a deep black luster to the polish when finished, and the graphite serves to impart the metallic luster to the treated article.

The varnish used will generally be a good quality of copal, but any other varnish possessing heat-resisting qualities may be substituted. Also, if desired, any other relatively slow drying oil may be employed in lieu of linseed oil.

This polish is especially adapted for either cast-iron surfaces or sheet metal surfaces. When it is to be used on sheet metal surfaces, the oily compound may be applied first to the surface to be polished, in liquid state, and before the addition of the graphite to the oily compound, and the surface t l which dried powdered graphite is applied and then polished according to the procedure disclosed in my patent for polishing metal granted April 4, 1911, Serial No. 988,664. When this polish is to be used on cast-iron surfaces, the graphite is mixed in the oily compound and applied in the regular way.

The proportions of the different ingredients given have been found to meet the necessary requirements; but it is to be understood that these may be varied to meet different conditions or contingencies that may arise, without departing from the spirit of the invention.

What is claimed is A metal polish consisting of the following ingredients in substantially the propor-
